Selena Gomez's PR reps confirmed to RadarOnline this morning that the singer underwent two weeks in rehab last month, dealing with "emotional issues" at The Meadows clinic in Arizona. Gomez entered rehab on January 5th, Radar reports, following months of "partying very hard." (And this matches a break in Selena's social media activity, which came to an abrupt halt at the beginning of January and later picked up again on the 20th.)

Though her representatives claimed Selena's stint at the Meadows was "not for substance abuse," a source told Radar she had been "experimenting" with marijuana and prescription drugs including Ambien and Xanax. Friends and family reportedly urged her to get some help and check out of the Los Angeles scene; Selena is also said to have recognized her "exhaustion," and "needed the opportunity to work on herself." And yes, Justin Bieber is named and shamed as a bad influence according to other insiders.
